How to install Subversion on DirectAdmin

ck — Sat, 12 May 2012 20:00:03 +0000

Subversion must be compiled against the Apache headers to create the mod_dav_svn module..

Apache doesn’t have a mod_dav_svn module and you can not install subversion with yum.

- Make a temp dir for your svn bits:

$mkdir /etc/customsvn
$cd /etc/customsvn

- Install libexpat and libneon:

$yum install expat-devel
$yum install neon-devel

- Get svn and unpack:

$wget http://archive.apache.org/dist/subversion/subversion-1.7.4.tar.gz
$tar xzf subversion-1.7.4.tar.gz
$mv subversion-1.7.4/* .
$rm -r subversion-1.7.4

- Get sqlite amalgamation and grab sqlite.c:

$mkdir sqlite-amalgamation
$cd sqlite-amalgamation
$wget http://www.sqlite.org/sqlite-amalgamation-3.6.13.tar.gz
$tar xzf sqlite-amalgamation-3.6.13.tar.gz
$mv sqlite-3.6.13/sqlite3.c

- Delete everything else:

$rm -rf sqlite-*
$cd ..

- Configure, make, install:

$./configure --prefix=/usr --with-apxs=/usr/sbin/apxs --with-apr=/usr/bin/apr-config
$make
$make install

- This should work now:

$svn help

- Remove loadmodule from httpd.conf:

$vi /etc/httpd/conf/httpd.conf

–> Add comments to these lines, we will do it in another conf file:
#LoadModule dav_svn_module /usr/lib/apache/mod_dav_svn.so
#LoadModule authz_svn_module /usr/lib/apache/mod_authz_svn.so

- Add an include to a new conf file:

$vi /etc/httpd/conf/extra/httpd-includes.conf

–> paste config
# All SVN directives
Include conf/extra/httpd-svn.conf

- Create the new conf file, put the loadmodules etc in here and change location properties according to your setup:

$vi /etc/httpd/conf/extra/httpd-svn.conf

–> paste config and change necessary places
LoadModule dav_svn_module /usr/lib/apache/mod_dav_svn.so
LoadModule authz_svn_module /usr/lib/apache/mod_authz_svn.so

      DAV svn
      SVNParentPath /svn

      AuthzSVNAccessFile /svn/authz
      Satisfy Any
      Require valid-user
      AuthType Basic
      AuthName "Subversion repository"
      AuthUserFile /svn/passwd

- Restart just to make sure all is good:

$service httpd restart

- Make an svn dir to match your config:

$mkdir /svn
$cd /svn

- Create a repo:

$svnadmin create projects

- Copy the authz file svnadmin made or write your own and add user to passwd file (specified in your httpd-svn config)

$cp projects/conf/authz .
$htpasswd -cm passwd demouser

- Give demouser read/write access to all repos:

$vi authz

–> Add at end of file
[/]
demouser = rw

- Give apache ownership of svn or commit will not work:

$chown -R apache:apache /svn

- Finally, restart:

$service httpd restart

If you got the following error when restarting apache:

Cannot load /usr/lib/apache/mod_dav_svn.so into server: libsvn_repos-?.so.?: cannot open shared object file: No such file or directory

This can be solved with ldconfig:

$ldconfig
$service httpd restart

How to use openssl for extracting private key ( .pem ) from .pfx

ck — Sun, 06 May 2012 19:47:37 +0000

You want to migrate your system from windows to linux and you got your SSL in .pfx from windows. You need private.key than you can use openssl for extracting .pem from .pfx (If you dont have openssl you can download from www.openssl.org).

For exporting private key ( .pem ) from PFX file and save it to PEM file :

$openssl pkcs12 -in /path/to/your_file_name.pfx -nocerts -out your_private_key_name.pem

If you want to remove the password from the private key file :

$openssl rsa -in your_private_key_name.pem -out your_new_private.pem

.PFX (Personal Information Exchange File):

Syntax Standard[11] Defines a file format commonly used to store private keys with accompanying public key certificates, protected with a password-based symmetric key. PFX is a predecessor to PKCS#12.

This container format can contain multiple embedded objects, such as multiple certificates. Usually protected/encrypted with a password. Usable as a format for the Java key store and to establish client authentication certificates in Mozilla Firefox. Usable by Apache Tomcat.

.PEM (Privacy Enhanced Mail):

Base64 encoded DER certificate, enclosed between "—–BEGIN CERTIFICATE—–" and "—–END CERTIFICATE—–"

Zimbra Unable to Determine Enabled Services From Ldap. Starting logger…Failed.

ck — Thu, 03 May 2012 06:52:41 +0000

[zimbra@ck]$ zmcontrol start
Host quote.cklog.net
        Starting ldap...Done.
Unable to determine enabled services from ldap.
Enabled services read from cache. Service list may be inaccurate.
        Starting logger...Failed.
Starting logswatch...ERROR: service.FAILURE (system failure: ZimbraLdapContext) (cause: javax.net.ssl.SSLHandshakeException sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target)
zimbra logger service is not enabled!  failed.

The usual reason for this error is expired SSL certificate..

This error usually happens if your SSL certificate has expired. There are two solutions for this problem.

The first solution is renewing your certificate and deploying it with the following command :

[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr deploycrt comm /opt/zimbra/ssl/zimbra/commercial/your_new_ssl.crt /path/to/ca_bundle.crt

After this you need to restart zmcontrol.

The second solution is regenerating self-signed certificate.

[zimbra@ck]$ su - zimbra -c 'zmcontrol stop'
[zimbra@ck]$ rm -rf /opt/zimbra/ssl/*
[zimbra@ck]$ rm -rf /opt/zimbra/ssl/.rnd
[zimbra@ck]$ /opt/zimbra/java/bin/keytool -delete -alias my_ca -keystore /opt/zimbra/java/jre/lib/security/cacerts -storepass changeit
[zimbra@ck]$ /opt/zimbra/java/bin/keytool -delete -alias jetty -keystore /opt/zimbra/mailboxd/etc/keystore -storepass `su - zimbra -c 'zmlocalconfig -s -m nokey mailboxd_keystore_password'`

Than Yo need to edit /opt/zimbra/bin/zmcertmgr file ( you can use ‘vi’ )

Find validation_days=365 and change to validation_days=3650

And save /opt/zimbra/bin/zmcertmgr

[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr createca -new
[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr deployca -localonly
[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr createcrt self -new
[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr deploycrt self
 
[zimbra@ck]$ su - zimbra -c 'zmcontrol start'
 
[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr deploycrt self
[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr deployca
 
[zimbra@ck]$ su - zimbra -c 'zmupdateauthkeys'
[zimbra@ck]$ /opt/zimbra/bin/zmcertmgr viewdeployedcrt

Finally, zimbra back to work

How to grep compressed files at a shell prompt?

ck — Sun, 29 Apr 2012 13:50:55 +0000

Sometimes you need to search inside of .gz files in your system. Unfortunately, grep is not working on compressed files. For solution people usually advise; uncompress file(s) than grep with your text and after that compress file(s) again…

You dont need to uncompress files. You can use zgrep on compressed or gzipped files.

To search in compressed file, execute the command :

zgrep 'put-your-text-here' /your-file-path-here/file.gz

Example : I want to grep ‘cklog’ in my all exim_rejectlog archive files.

root@ck [~]# ls /var/log
./                        
../
exim_rejectlog.1.gz
exim_rejectlog.2.gz
exim_rejectlog.3.gz
exim_rejectlog.4.gz                 
root@ck [~]# zgrep 'cklog' /var/log/exim_rejectlog.*

How to export Mailman Subscriber List from Cpanel/Whm?

ck — Sat, 28 Apr 2012 16:57:56 +0000

Cpanel’s Mailman is a open-source mailing list application. The problem is no easy way to export subscribers from list..

Step 1: Login into account via SSH ( as root ).
Step 2: Find mailman directory. ( Default Location : /usr/local/cpanel/3rdparty/mailman/bin )

cd /usr/local/cpanel/3rdparty/mailman/bin

Step 3: Execute the following command to export subscribers to a text file:

./list_members yourlistname > ./export_file_name.txt

Example Mailman List Name : maillist_cklog.net ( If my subscriber list is maillist@cklog.net, the listname would be maillist_cklog.net )

This command will export my email subscribers into file ( export_file_name.txt ).

Setting up roundcube to webmail.domain.com as default for domains in directadmin

ck — Fri, 02 Mar 2012 23:20:49 +0000

You need to setup the virtualhost for apache2.

[root@ck]# cd /usr/local/directadmin/data/templates
[root@ck]# cp virtual_host2.conf custom
[root@ck]# cd custom

Now you can edit the new virtual_host2.conf (apache 2) file in custom folder and just add the codes to the end.

Simply save and exit. Then run below to rewrite the httpd.conf files.

echo "action=rewrite&value=httpd" >> /usr/local/directadmin/data/task.queue /usr/local/directadmin/dataskq d

Finally you need to setup dns part.

[root@ck]# cd /usr/local/directadmin/data/templates
[root@ck]# cp dns_a.conf custom
[root@ck]# cd custom
[root@ck]# echo "webmail=|IP|" >> dns_a.conf

Note: Please check custom folder if there is a file with dns_a.conf name. Also dont forget that is only setup webmail A record for new domains. For existing domains, you’ll have to add manually.
